To all whom it may concern:

Be it known that I, ORVILLE R VAN VECHTEN, a citizen of the UnitedStates, and a resident of New Brighton, borough of Richmond, county ofRichmond, and State of New York, have invented certain new and usefulImprovements in Braiding- Machines, of which the following is a full,clear, and exact description.

This invention relates to a'thread take-up for tubular braiding machinesof that type in which two circular series of thread bob.- bins areemployed, one series moving around the machine in one direction and theother moving around in the opposite direction, and wherein it isdesirable to have radially reciprocating thread guides in order tosecure the proper interweaving or bra1ding of the threads. A machine ofthis type, and to which this take-up is particularly adapted, is shownin the application filed by Ralph W, Lotz on the 11th day of June, a

1917, Serial N 0. 173,982.

One of the objects of this invention is to provide a simple, positiveand efficient thread take-up which may be adjusted to vary the amount ofthe take-up to correspond with the variations in the diameter of thetubular fabric being braided.

Another object of the invention is to provide a radially reciproeablethread guide and carrier, and a relatively stationary thread guide, thereciprocating guide and the relatively stationary guide being soarranged with respect to each other than there will be the desiredamount of take-up and let-0E in the thread during the operation of themachine.

There are other objects and advantages of the invention which willappear more fully hereinafter.

cally adjustable relatively stationary thread guide.

Fig. 7 a detail edge view of the rotatable table carrying the take-updevices.

Referringto the various parts by numerale, 1 designates the main frameof the machine, which is suitably supported on standards. The main frameis circular and conextending annular side flange 2, said frame forming acircular receptacle to receive most of the operating parts. In the mainframe, and substantially flush with the upper edge of the side flangethereof is mounted a circular rotatable table at. Connected to the underside of this table, and concentric therewith is a circular plate 5, saidplate being formed with a central depending hub. Connected to the lowerend of the hub of this plate 5 is a gear wheel 6, said wheel beingconcentric with the table and bearing on a central hub formed on thebase plate 3 of the main frame. A tubular spindle 3 is rigidly securedin the base plate 3 and extends upwardly through central apertures inthe gear 6, connecting plate 5, and the table 4-, the said partsrotating about said spindle. The gear 6 is rigidly connected to theplate 5, and said plate is rigidly connected to the table 4 so that allof said parts rotate together. Meshing with the gear 6 is anintermediate, drive gear 7, whlch in turn meshes with the main drivinggeart8 mounted upon a vertical shaft 9, journaled in suitable bearingson the side of the main frame. To the lower end of this vertical shaftis secured a beveled pinion 10, which meshes with a similar pinion 11secured to a horizontal shaft 12, which carries the driving belt wheel13. Engaging this belt wheel is the movable member 14; of a frictionclutch, said clutch being operated by means of a lever 15, one arm ofwhich ex tends up into the machine and is operated The table 4 is'formedwith radial slots 16 which extend from a point near the center of thetable to the periphery thereof, the outer ends of said slots being open.Mounted on the table between said slots is a series of spools 17, saidspools being located be tween the slots and at a suitable distancefromthe center of the table. Formed on the table near the peripherythereof is an annular flanged track 18, said track being interrupted bythe radial slots, and extending only between said slots. Mounted toslide on this track are carriers 19, each of said carriers carrying avertical bobbin 20. The carriers are free to slide on the track 18, andare of sufiicient length to bridge the breaks in the track due to theradial slots 16.

In each slot 16 is mounted a radially movable slide 21 and each slidecarries at its outer end a vertical post 22, which carries near itslower end a thread guide 23, a simiupper end thereof.

lar thread guide 24 being mounted on the On the inner end of each slideis mounted a thread guide 25. In front of this guide 25 is mounted apawl which is held out of engagement with an automatic stop by thethread. Should the thread break, the pawl will drop and engage theautomatic stop. As the automatic stop forms no part of this invention itneed not be fully described herein. From the guide 25. the thread passesupwardly to a guide 26, mounted on a rigid post 27 carried by the table.From this latter guide the thread passes. inwardly to a guide 28 securedrotatably on the upper end of a rigid post carried by thetable 4L.

In the plate 5 near the periphery thereof is. mounted a vertical shaft29, on the lower end of which is secured a pinion 30 which meshes with afixed annular rack 31, said rack being supported by lugs on the baseplate 3 of the machine. On the upper end of the shaft 29 is mounted acrank 32, the outer end of which is connectedby a link 33 to the slide21. It is manifest that as the table A and plate 5 are rotated the gear30 will be rotated on its axis and the connected slide 21 reciprocatedin its slot by means of the crank 32 and the link 33. As shown in thedrawings, when the slide 21 is at the limit ofits outward movement thethread guide .post 22 has been carried outwardly beyond. the track 18and the carrier mounted thereon, and the thread 17 from the spool 17 is.carried outwardly beyond the thread 20 of the/bobbin 20, and is in aposition to be passed over the thread 20 When the slide 21 is at theinner limit of its movement, thethread guide post 22 is carried inwardlythrough the slots in the track 18, and the thread 17*- is in a positionto. be As he l d 21 is moved outwardly, the post 22 may be engaged by asuitable escapement mechanism and passed around the carriers.

Itis manifest that the thread guide 25 as it passes inwardly beyond thethread guide 26serves as a take-up device to take up the slack in thethread l'i' 'due to the movement of the. slide inwardly beyond thethread de 26 T fnrq i afp i an as ur te take-rip, and o v ates he neeesr f uses sprmss er eight is tales the slack in the thread,'which slackis due to the reciprocation of the thread guides and slides. The threadguide 26 is vertically adjustable in the slotted post 27 in order tovary the amount of take-up. This adjustment is made necessary wheneverthe diameter of the tubular fabric is changed. It is clear that whencovering a core of large diameter there will be less slack to be takenup upon the inward movement of the thread guide post 22. By adjustingthe thread guide 26 upwardly in the post 27 the amount of thread takenup upon the inward movement of the slide will be reduced; and bylowering the thread guide 26 the amount of slack taken up upon theinward movoment oi the slide 21. will be increased. It is obvious,therefore, that when braiding over a core of large diameter the threadguide 26 will. be in. an elevated position, whereas when braiding over acore of small diameter, the said thread guide will be in a loweredposition.

The drawings illustrate only one-half of a braiding machine, but it willof course, be understood that the two halves are precisely alike. Onlyone slot is shown in the rotatable table, and only one slide and itsoperating mechanism is illustrated. There may be asanany slides asdesired, each slide, of course, operating in a radial slot.
